Aim: To evaluate doctors' knowledge, attitude, and practices and predictors of adherence to Malaysian hypertension guidelines (CPG 2008).
Methods: Twenty-six doctors involved in hypertension management at Penang General Hospital were enrolled in a cross-sectional study. Doctors' knowledge and attitudes towards guidelines were evaluated through a self-administered questionnaire. Their practices were evaluated by noting their prescriptions written to 520 established hypertensive outpatients (20 prescriptions/doctor). SPSS 17 was used for data analysis.
Results: Nineteen doctors (73.07%) had adequate knowledge of guidelines. Specialists and consultants had significantly better knowledge about guidelines' recommendations. Doctors were positive towards guidelines with mean attitude score of 23.15 ± 1.34 points on a 30-point scale. The median number of guidelines compliant prescriptions was 13 (range 5-20). Statistically significant correlation (rs = 0.635, P < 0.001) was observed between doctors' knowledge and practice scores. A total of 349 (67.1%) prescriptions written were guidelines compliant. In multivariate analysis hypertension clinic (OR = 0.398, P = 0.008), left ventricular hypertrophy (OR = 0.091, P = 0.001) and heart failure (OR = 1.923, P = 0.039) were significantly associated with guidelines adherence.
Conclusion: Doctors' knowledge of guidelines is reflected in their practice. The gap between guidelines recommendations and practice was seen in the pharmacotherapy of uncomplicated hypertension and hypertension with left ventricular hypertrophy, renal disease, and diabetes mellitus.

Background: To assess the performance of different GFR estimating equations, test the diagnostic value of serum cystatin-C, and compare the applicability of cystatin-C based equation with serum creatinine based equation for estimating GFR (eGFR) in comparison with measured GFR in the elderly Malaysian patients.
Methods: A cross-sectional study recruiting volunteered patients 65 years and older attending medical outpatient clinic. 51 chromium EDTA (51Cr-EDTA) was used as measured GFR. The predictive capabilities of Cockcroft-Gault equation corrected for body surface area (CGBSA), four-variable Modification of Diet in Renal Disease (4-MDRD), and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations using serum creatinine (CKD-EPIcr) as well as serum cystatin-C (CKD-EPIcys) were calculated.
Results: A total of 40 patients, 77.5% male, with mean measured GFR 41.2 ± 18.9 ml/min/1.73 m2 were enrolled. Mean bias was the smallest for 4-MDRD; meanwhile, CKD-EPIcr had the highest precision and accuracy with lower limit of agreement among other equations. CKD-EPIcys equation did not show any improvement in GFR estimation in comparison to CKD-EPIcr and MDRD.
Conclusion: The CKD-EPIcr formula appears to be more accurate and correlates better with measured GFR in this cohort of elderly patients.

Background: The elderly population is the largest consumer of medications as this age group is at high risk for developing chronic diseases. However, medication use among elderly people is complicated by an increased risk of drug-related problems. Therefore, the present study was conducted to investigate the effects of collaborative interventions between pharmacists and physicians on health-related outcomes of elderly patients.
Patients and methods: This was a randomized controlled trial (RCT) conducted on elderly outpatients who sought treatment in the Medical Outpatient Department of a public tertiary hospital in Malaysia and who were taking at least five medications. The participants were randomly allocated to the intervention and control groups. The intervention group received pharmaceutical care from a pharmacist in collaboration with physicians and was followed-up for 6 months, while the control group received usual care in the outpatient pharmacy.
Results: A total of 73 participants in the intervention group and 79 participants in the control group completed the study. Participants in the intervention group had significantly better medication adherence (median =7.0 vs 5.0, U=1224.5, p<0.001, r=0.503) and better Medication Appropriateness Index (MAI) score (median =8.0 vs 20.0, U=749.5, p<0.001, r=0.639).
Conclusion: Collaborative interventions between pharmacists and physicians improved medication adherence and MAI scores of the elderly patients. Therefore, such services should be implemented in all hospitals, especially in countries where pharmacists are still not playing a substantial role in patient care.

Rheumatoid arthritis (RA) is a chronic inflammatory condition that can be associated with abnormal bone turnover and hence osteoporosis. Osteocalcin (OC) levels are increased in conditions with high bone turnover, including high RA disease activity. Thus, OC levels could possibly be used as a marker to assess bone health and disease activity in RA patients. As there have been no previous studies looking at serum OC levels in Malaysian RA patients, this study was performed to examine possible correlations between OC, bone mineral density (BMD) and disease activity in this population. A cross-sectional study of 75 female RA patients and 29 healthy controls was performed. Serum OC was measured using a Quantikine® ELISA kit. Dualenergy x-ray absorptiometry (DXA) was used to assess BMD. Serum OC levels were not significantly different between RA patients (median 14.44 ng/mL, interquartile range [IQR 12.99]) compared to healthy controls (median 11.04 ng/mL IQR 12.29) (p=0.198). Serum OC increased with age (Spearman’s rho r=0.230, p=0.047). There was no significant correlation between serum OC and body mass index (BMI), menopause status, BMD, DAS28, swollen or tender joint counts. Overall, there were 11 (14.7%) patients with osteoporosis and 27 (36.0%) with osteopenia. Menopause status was significantly associated with BMD at all sites (lumbar spine p=0.002, femoral neck p=0.004, total hip p=0.002). Serum OC were similar in RA patients compared to healthy controls. In RA patients, serum OC did not correlate with RA disease activity or BMD. Menopause status remains an important influence on BMD. Thus, measuring serum OC levels in Malaysian RA patients was not useful in identifying those at risk of low BMD.

Purpose: To examine the trends of analgesic prescribing at public tertiary hospital outpatient settings and explore the patterns of their utilization in nonsteroidal anti-inflammatory drugs (NSAIDs), tramadol, and opioid patients.
Patients and methods: This cross-sectional study was conducted from 2010 to 2016 using the prescription databases of two tertiary hospitals in Malaysia. Prescriptions for nine NSAIDs (ketoprofen, diclofenac, celecoxib, etoricoxib, ibuprofen, indomethacin, meloxicam, mefenamic acid, and naproxen), tramadol, and five other opioids (morphine, fentanyl, oxycodone, dihydrocodeine, and buprenorphine) were included in this study. Annual number of patients and prescriptions were measured in repeat cross-sectional estimates. Descriptive statistics and linear trend analysis were performed using Stata version 13.
Results: A total of 192,747 analgesic prescriptions of the nine NSAIDs, tramadol, and five other opioids were given for 97,227 patients (51.8% NSAIDs patients, 46.6% tramadol patients, and 1.7% opioid patients) from 2010 to 2016. Tramadol (37.9%, n=72,999) was the most frequently prescribed analgesic, followed by ketoprofen (17.5%, n=33,793), diclofenac (16.2%, n=31,180), celecoxib (12.2%, n=23,487), and other NSAIDs (<4.5%). All the analgesics were increased over time except meloxicam, indomethacin, and mefenamic acid. Opioids, primarily morphine (2.2%, n=4,021) and oxycodone (0.5%, n=1,049), were prescribed the least, but the rate of increase was the highest.
Conclusion: Tramadol was the most frequently prescribed analgesic in hospital outpatient settings in Malaysia. Opioids were prescribed the least, but noted the highest increase in utilization.

Purpose: The objective of this study was to explore the experiences and side-effects of breast cancer patients on chemotherapy in Malaysia.
Participants and methods: Purposive sampling of 36 breast cancer patients who have completed chemotherapy and agreed to participate in semi-structured in-depth interviews. A constant comparative method and thematic analysis were used to analyze the interviews.
Results: Data were categorized into six main themes: know nothing of chemotherapy; fear of chemotherapy; patients' beliefs in alternative treatments; symptom management; staying healthy after chemotherapy; and concerns of patients after chemotherapy.
Conclusion: Despite complaints about the bad experiences of their chemotherapy-induced side-effects, these patients still managed to complete the entire course of chemotherapy. Moreover, there is a need for a clinical pharmacy service in the oncology clinic setting in Malaysia in order to provide relevant information to help patients understand the chemotherapy received.

Diabetes Mellitus has become one of the major and rising diseases affecting population all around the world. The most common complication that rises from the Diabetes Mellitus is diabetic foot ulcer. The increasing rate in diabetic foot ulcer among elderly has become a challenge that continues to rise and worsen. This study is conducted to determine the knowledge and practice of foot care and also the relationship between socio demographic data with knowledge of foot care among diabetic elderly in UKM Medical Centre (UKMMC). This is a quantitative cross-sectional descriptive study. A total of 81 respondents are being participated in this study. More than half of the study participants are female and majority of them are 60-74 years old. The result showed a significant relationship between gender and marital status with the knowledge of foot care among elderly diabetic patient in UKMMC. The present study showed that there was no significantly relationship between age, occupation, monthly income, duration of diabetes, body image and level of education with the knowledge and the level of foot care. In conclusion, the result of this study will help the health organization, hospital, nurses and care giver to take more responsibilities of foot care for diabetic elderly individuals.

Introduction: Hyperuricemia is associated with chronic kidney disease (CKD) progression and poor cardiovascular outcomes. We studied the effect of febuxostat on estimated glomerular filtration rate (eGFR), proteinuria and monitored the safety profile of the medication.
Material and Methods: This is a prospective open-label, randomized study in CKD stage 3 and 4 patients with diabetic nephropathy and asymptomatic hyperuricemia. Patients were randomized into febuxostat 40 mg daily and no treatment group using block randomization method and were followed up for 6 months. Their usual care for diabetes mellitus, hypertension and dyslipidemia were continued in the study. Blood and urine investigations were monitored at baseline, 3 months and 6 months.
Results: The eGFR in febuxostat group was stabilized at 6 months with no significant reduction [26.2 (IQR 14.30) at baseline to 26.3 (IQR 15.2) ml/min/1.73 m2]. Whereas, there was a significant reduction of the eGFR in no treatment group from 28.2 (IQR 17.9) to 27.6 (IQR 19.3) ml/min/1.73 m2 (p value < 0.01). We found the HbA1c (glycosylated hemoglobin) was significantly increased in febuxostat group from 7.2 ± 0.5 % at baseline to 7.6 ± 1.4 at 6 months (p value 0.04) but no significant change of HbA1c in the no treatment group. Proteinuria level was unchanged in both groups. The commonest adverse event was joint pain.
Conclusions: Febuxostat was able to preserve eGFR in CKD patients with diabetic nephropathy and this effect was beyond glycemic control. Increment of HbA1c level in febuxostat group needs further larger trials.

Adverse drug reaction (ADR) primarily caused by many drugs including antibiotics. At present, the incidence and pattern of ADR caused by antibiotics have remained as neglected area in Malaysia. This study was conducted to determine the incidence and analyze the pattern of ADR caused by antibiotics among patients in a tertiary care hospital. It is a 2-year retrospective observational study conducted at Hospital Pulau Pinang, Malaysia. All eligible patients who had antibiotic prescribed belonging to any age group either from outpatient or inpatient that had experienced ADR was included in this study. The outcomes were measured with the aid of Naranjo's and Hartwig's scales. The incidence of the ADRs among patients prescribed with antibiotics in Hospital Pulau Pinang is about 1.1%. Vancomycin and Trimethoprim/Sulfamethoxazole both are considered to be the major contributors to ADR incidences. The skin was the most affected organ by ADRs followed by gastrointestinal system. Most of the severe ADRs were caused by Penicillin. The causality relationship of all the severe reactions was mostly probable. General Medicine unit had reported the highest number of ADRs caused by antibiotics. The common manifestations of ADRs are acute kidney injury and exanthem. In addition, majority of the ADRs caused by antibiotics were reversible. A large multicenter study is suggested to confirm the present findings.
OBJECTIVE: To determine the effectiveness of an individually-tailored multifactorial intervention in reducing falls among at risk older adult fallers in a multi-ethnic, middle-income nation in South-East Asia.
DESIGN: Pragmatic, randomized-controlled trial.
SETTING: Emergency room, medical outpatient and primary care clinic in a teaching hospital in Kuala Lumpur, Malaysia.
PARTICIPANTS: Individuals aged 65 years and above with two or more falls or one injurious fall in the past 12 months.
INTERVENTION: Individually-tailored interventions, included a modified Otago exercise programme, HOMEFAST home hazards modification, visual intervention, cardiovascular intervention, medication review and falls education, was compared against a control group involving conventional treatment.
PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was any fall recurrence at 12-month follow-up. Secondary outcomes were rate of fall and time to first fall.
RESULTS: Two hundred and sixty-eight participants (mean age 75.3 ±7.2 SD years, 67% women) were randomized to multifactorial intervention (n = 134) or convention treatment (n = 134). All participants in the intervention group received medication review and falls education, 92 (68%) were prescribed Otago exercises, 86 (64%) visual intervention, 64 (47%) home hazards modification and 51 (38%) cardiovascular intervention. Fall recurrence did not differ between intervention and control groups at 12-months [Risk Ratio, RR = 1.037 (95% CI 0.613-1.753)]. Rate of fall [RR = 1.155 (95% CI 0.846-1.576], time to first fall [Hazard Ratio, HR = 0.948 (95% CI 0.782-1.522)] and mortality rate [RR = 0.896 (95% CI 0.335-2.400)] did not differ between groups.
CONCLUSION: Individually-tailored multifactorial intervention was ineffective as a strategy to reduce falls. Future research efforts are now required to develop culturally-appropriate and affordable methods of addressing this increasingly prominent public health issue in middle-income nations.
Introduction The availability of obesity specific quality of life measurement tool is limited. The Malay version of Impact of Weight on Quality of Life-Lite is an obesity specific quality of life questionnaire which has been translated for use in Malaysia. The aim of this study is to evaluate the validity and reliability of this questionnaire to measure quality of life among different body mass index (BMI) groups.
Methods One hundred and twenty subjects with different BMI categories who attended an outpatient government clinic were recruited for this study. The translated Malay version of IWQOL-Lite was used to assess the impact of weight on quality of life of respondents. Content validity, criterion validity and construct validity were used to assess the questionnaire validity while internal consistencies and test-retest reliability were used to assess the questionnaire reliability.
Results The Malay version of IWQOL-Lite showed good psychometric properties. The content validity was agreed upon by expert panels. The mean score of all IWQOL-Lite domains were able to discriminate between different BMI groups. Good internal consistency was demonstrated by Cronbach alpha of 0.936. Test-retest reliability ranged from 0.828 to 0.932. The physical function score (IWQOL-Lite) correlated positively with Physical Component Summary of Short Form-36 questionnaire. Exploratory factor analysis found that the questions loaded on their respective five domains.
Conclusions The results suggested that the Malay version of IWQOL-Lite is a valid and reliable tool to measure quality of life among obese and overweight subjects in Malaysia.
Background: Respiratory Medication Therapy Adherence Clinic (RMTAC) is an initiative by the Ministry of Health (MOH) Malaysia to improve patients' medication adherence, as an adjunct to the usual physician care (UC). This study aimed to evaluate the cost-effectiveness of combined strategy of RMTAC and UC (RMTAC + UC) vs. UC alone in asthma patients, from the MOH Malaysia perspective.
Methods: A lifetime horizon dynamic adherence Markov model with monthly cycle was developed, for quality-adjusted life year (QALY) gained and hospitalization averted outcomes. Transition probabilities of composite asthma control and medication adherence, utilities, costs, and mortality rates due to all causes were measured from local data sources. Effectiveness, exacerbation rates, and asthma mortality rates were taken from non-local data sources. One-way sensitivity analysis (SA) was conducted for assessing parameter uncertainties, whereas probabilistic SA (PSA) was conducted on a different set of utilities and effectiveness data. Costs were adjusted to 2014 US dollars ($). Both costs and benefits were discounted at a 3% rate annually.
Results: RMTAC + UC was found to be a dominant alternative compared to UC alone; $- 13,639.40 ($- 109,556.90 to $104,445.54) per QALY gained and $- 428.93 ($- 521.27 to ($- 328.69)) per hospitalization averted. These results were found to be robust against changes in all parameters except utilities in the one-way SA, and for both scenarios in PSA.
Conclusions: RMTAC + UC is more effective and yet cheaper than UC alone, from the MOH perspective. For the benefit of both MOH and patients, RMTAC is thus recommended to be remained, and expanded to more healthcare settings where possible.
Introduction Parkinson’s disease (PD) is the second most common neurodegenerative disease after Alzheimer’s disease (AD) and the most frequent sub-cortical degenerative disease, characterized by universal progressive disorder of the
nervous system that affects movement. This cross sectional study aimed to determine the prevalence and correlates of PD among elderly attending the neurology clinic in Serdang Hospital.
Methods A total of 150 records of patients attended the clinic from January to December 2016 were randomly selected. Data was collected using a proforma form seeking information related to age, gender, race, locality, and presence of comorbidity particularly diabetes mellitus. The data was analysed using the Statistical Package for Social Science (IBM SPSS) version 22.0.
Results The prevalence of PD among the elderly involved in the study was 34%. Majority of the respondents were aged 60 to 70 years old (54.7%), male (53.3%), Chinese (56.7%), from urban locality (93.0%) and were not diabetic (69.3%). The inferential statistics showed no significant association between all the factors with PD. However, the associations between age and diabetes mellitus with PD were almost significant with p values of 0.07 and 0.08 respectively.
Conclusions Overall, the prevalence of PD among elderly who attended the neurology clinic in year 2016 was less than half with none of the factors under study were significantly associated with PD. However with bigger sample size, possible significant association may be obtained between age and diabetes mellitus.
In Malaysia, chest radiograph is a part of compulsory investigations during routine medical examination. Majority of these chest radiographs are interpreted by medical officers at the outpatient clinic. This study was to determine the concordance of chest radiograph interpretations between medical officers and radiologist. Medical officers' report of routine chest radiographs at the outpatient clinic Hospital Universiti Sains Malaysia over a 6-month period were compared to that of a radiologist. Of 408 chest radiographs reported, the concordance of interpretation between medical officers and radiologist was 93.6% (382 of 408). Medical officers correctly interpret 98.2% (378/385) of normal chest radiograph compared to 17.4% of abnormal chest radiographs (4/23). Therefore, routine chest radiograph interpretations of normal radiographs by medical officers were generally accurate. However, they were weak in interpreting abnormal chest radiographs. Medical officers need to be trained on detecting abnormalities on chest X-ray since most routine chest X-ray reporting is done based on their interpretation.

Introduction: Good control of glycaemia negates potential maternal and fetal complications. A diet suitable for women with gestational diabetes mellitus (GDM) is a first line approach. However, little is said about suitable exercise in pregnancy that will potentially help control glycaemia. This pilot study seeks to understand the perceived barriers to exercise in women with GDM.
Materials and Methods: This crosssectional study recruited patients with GDM on diet control at the antenatal clinic of Hospital Sultanah Aminah Johor Bahru, Malaysia between October 2017 and January 2018. Those who fulfilled the recruitment criteria were approached and 89 women consented to participate. Data was obtained from antenatal records and a self-administered questionnaire.
Results: The mean age of the participants was 33.3 years. More than 80% were Para 1 and above. 69.6% were either overweight or obese at booking of pregnancy. 80.9% were aware that exercise was necessary for women with GDM. Only 6.7% say that healthcare professionals were their source of information on exercise in pregnancy. 77.3% of the women with low physical activity had full time jobs. Housewives (64.5%) had the highest level of physical activity. Tiredness (43.8%), childcare duties (38.2%) and lack of time (27.0%) were the most common perceived barriers to exercise. Nulliparity was significantly associated with tiredness.
Conclusion: Main barriers to exercise are tiredness and childcare duties. Health care professionals did little in educating women with GDM on suitable exercise.
Diabetes is a chronic complicated disease. For that reason, self-care management and education are necessary to control blood glucose levels to decrease mortality and morbidity rate, the risk of complications and adverse medication related events. Lack of knowledge about a diabetic medication and non-adherence contribute to poor glycemic control among diabetes patients. Therefore, this study aims to assess relationship between medication knowledge and medication adherence among T2DM. A cross sectional study was carried out in outpatient's diabetic clinic in University Malaya Medical Centre via recruiting 250 participants. A set of questionnaires from earlier research were used to collect the data. Descriptive and inferential statistical analysis is used to analyze the data. The inclusive results indicated that, the mean age of the participants was 57.90 ±13.22 within 56years. More than half of patients (52.5%) had poor medication knowledge, and 47.5% had good knowledge. In terms of medication adherence, most of the participants (87.0%) had medium medication adherence; whereas, only 1.3% showed high medication adherence. However, there was no correlation between medication knowledge and medication adherence (p=0.743). The chi-square results indicated that medication knowledge was associated significantly with gender, educational level, employment status and monthly income (p value < 0.05). In conclusion it can be said that this study provides insight for healthcare professional about medication knowledge and adherence which are important for managing diabetes. Awareness of these factors will allow them to be more effective about medication counseling so that patients can become self-responsible and realize the benefits of prescribed therapies.

Hyperalgesia is a common clinical phenomenon among opioid dependent patients on methadone maintenance therapy (MMT) and it may be associated with undertreated pain and/or therapeutic failure. This study aimed to investigate association between serum methadone concentration (SMC) and cold pressor pain responses. Cold pressor pain responses in 147 opioid dependent patients on MMT were assessed using cold pressor test (CPT) at 0 h and at 2, 4, 8, 12, and 24 h after the dose intake. Blood samples were collected at 24 h after the dose. Serum methadone concentrations were measured using the Methadone ELISA kit and classified into two categories: < 400 ng/mL and ≥ 400 ng/mL. Eighty-eight patients (59.9%) had trough concentrations of < 400 ng/mL and 40.1% had trough concentrations of ≥ 400 ng/mL. There were significant effects of SMC on the cold pressor pain threshold (p = 0.019). Patients with concentrations < 400 ng/mL had significantly higher (almost 60% higher) cold pressor pain threshold (adjusted mean (95% CI) = 30.15 (24.29, 36.01) s) compared to those with concentrations of ≥ 400 ng/mL (18.93 (11.77, 26.08) seconds). There was also a 20% difference in pain tolerance, and 6% difference in cold pressor pain intensity score, neither of which were significant statistically (p > 0.05). Our results suggest an association of trough methadone concentration with the cold pressor pain threshold among opioid dependent patients on MMT. It would be useful to study the mechanisms underlying this association to help managing pain in such a population.

BACKGROUND: Accurate measurement of renal function is important: however, radiolabelled gold standard measurement of GFR is highly expensive and can only be used on a very limited scale. We aim to compare the performance of Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) equations in the multi-ethnic population attending University Malaya Medical Centre (UMMC).
METHODS: This is a cross-sectional study recruiting patients, who attend UMMC Nephrology clinics on voluntary basis. 51-Chromium EDTA (51Cr-EDTA) plasma level was used to measure the reference GFR. The serum creatinine was determined by IDMS reference modified Jaffe kinetic assay (CrJaffe). The predictive capabilities of MDRD and CKD-EPI based equations were calculated. Data was analysed using SPSS version 20 and correlation, bias, precision and accuracy were determined.
RESULTS: A total of 113 subjects with mean age of 58.12 ± 14.76 years and BMI of 25.99 ± 4.29 kg/m2 were recruited. The mean reference GFR was 66.98 ± 40.65 ml/min/1.73m2, while the estimated GFR based on MDRD and CKD-EPI formula were 62.17 ± 40.40, and 60.44 ± 34.59, respectively. Both MDRD and CKD-EPI were well-correlated with reference GFR (0.806 and 0.867 respectively) and statistically significant with p
BACKGROUND: This study evaluates the psychometric properties of the Malay version of the Brief Psychiatric Rating Scale (BPRS-M) among patients with schizophrenia in a psychiatric outpatient clinic.
METHODS: Ninety-nine schizophrenia outpatients were administered the Malay version of the Brief Psychiatric Rating Scale (BPRS-M), Malay version of Positive and Negative Syndrome Scale (PANSS), Malay version of Calgary Depression Scale for Schizophrenia (CDSS) and Malay version of World Health Organization Quality of Life - Brief Version (WHOQOL-BREF).
RESULTS: An exploratory factor analysis (EFA) of BPRS-M produced a seven-factor solution which accounted for 71.4% of the total variance. It exhibited fair internal consistency (Cronbach's alpha coefficient of 0.75). "Positive symptoms" and "Resistance" factors had association with unemployment and number of antipsychotics, positively correlated with PANSS but negatively correlated with WHOQOL-BREF. "Mood disturbance" factor correlated with lifetime history of suicide attempts, Malay version of CDSS and WHOQOL-BREF (psychological). Both "Negative symptoms" and "Activation" factors were associated with male, lower education, unemployment and positively correlated with Malay version of PANSS but negatively correlated with WHOQOL-BREF.
CONCLUSIONS: The BPRS-M demonstrated promising psychometric properties in terms of dimensionality, reliability, and validity that generally justifies its use in routine clinical practice in Malaysia.

BACKGROUND AND OBJECTIVE: Mycophenolic acid (MPA) provides effective treatment for lupus nephritis patients. Owing to its large pharmacokinetic variability, it is questionable whether standard fixed dose therapy can achieve optimal MPA exposure. The aim of this study was to develop a population pharmacokinetic model of MPA and its metabolite, 7-O-MPA-β-glucuronide (MPAG), to identify important covariate influences and better predict patient dosing requirements.
METHODS: MPA and MPAG concentration-time profiles were collected from 25 patients receiving mycophenolate mofetil (MMF) with or without cyclosporine (CsA) co-therapy. Samples were collected pre-dose and at 1, 2, 4, 6 and 8 h post-dose on one or two occasions.
RESULTS: A total of 225 and 226 concentration-time measurements of MPA and MPAG, respectively, were used to develop the model, utilizing NONMEM® software. A two-compartment model with first-order absorption and elimination for MPA and a one-compartment model with first-order elimination and enterohepatic circulation (EHC) for MPAG best described the data. Apparent clearance of MPAG (CL/F MPAG) significantly decreased with reducing renal function and extent of EHC was reduced with concomitant CsA use. Simulations using the final model showed that a 70-kg subject with a creatinine clearance of 90 mL/min receiving concomitant CsA would require 1.25 g of MMF twice daily while a similar subject who did not receive concomitant CsA would require 0.75 g twice daily to achieve a MPA area under the concentration-time curve from 0 to 12 h (AUC0-12) of 45 mg·h/L.
CONCLUSION: A 'tiered' dosing approach considering patient renal function and CsA co-therapy, rather than a 'one dose fits all' approach, would help individualize MMF therapy in adult lupus nephritis patients to ensure more patients have optimal MPA exposure.
